VALVE.

Specification of Letters Patent.

Patented Get. 16, 19170.

Application filed May 22, 1917. Serial No. 170,235.

T 0 all whom it may concern:

Be it known that I, DAvID L. WINTERS, a citizen of .the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inValves, of which the following is a specification.

This invention relates to valves and more particularly to throttlevalves or attachments adapted to be used in connection with gas enginesof the explosive type.

Because of the comparatively low grade gasolene now being used, thecharge, as it passes from the carbureter to the engine, contains smallglobules of fuel, which have not been thoroughly atomized, or vaporized.

This is especially the case in cold weather,

or when only a small amount of power isrequired since the velocity ofthe air through the mixing chamber of the carbureter at such times, isnot sufficient to thoroughly vaporize the fuel.

Incomplete combustion, together with an undue accumulation of carbon inthe cylinders of the engine, always accompanies the use of a charge thathas not been suificiently vaporized.

This condition is well known to manufacturers of motor cars, and tocompensate for the additional waste of fuel in this manner in coldweather, they recommend a readjustment of the fuel valve that willsupply the engine with the additional fuel that is thus wasted.

It is one of the objects of this invention to vaporize or atomize thatportion of the fuel which 'has not been properly vaporized or atomizedin the mixing chamber of the carbureter.

Another object of the present invention is to provide a simple andpractical attachment in the nature of a valve adapted to be placed inthe manifold leading from the carbureter to the engine which will bemore reliable and eflicient in use and operation than devices-now inuse. A further object is to provide a device of the above generalcharacter having relatively few parts which will be inexpensive tomanufacture and may be installed in engines now in use without materialexpense. A further object is to provide a device of the first abovementioned character adapted to produce a most thorough and intimatemixing of the air and gasolene and to fully and completely vaporize thegasolene prior to the entrance of the explosive mixture into thecylinder.

Other objects will be in part obvious from the annexed drawings and inpart indicated in connection therewith by the following analysis of thisinvention.

This invention accordingly consists in the features of construction,combination of parts and in the unique relations of the members and inthe relative proportioning and dispositionthereof, all as morecompletely outlined herein.

To enable others skilled in the art so fully to comprehend theunderlying features thereof that they may embody the same by thenumerous modifications in structure and relation contemplated by thisinvention, drawings depicting a preferred form and and also amodification have been annexed as a part of this disclosure, and .insuch drawings like characters of reference denote corresponding partsthroughout all the views, in which- Figure l is a view partly in sectionof the device and associated parts of an engine;

Fig. 2 is a'vertical transverse sectional View showing the device inoperative position in the manifold of the engine, taken on the line 22,Fig. 1; I

Fig. 3 is an enlarged detail sectional view;

Fig. i is a sectional view of modification.

Referring now to the drawings in detail and more particularly to Fig. 1,5 denotes the manifold leading from a carbureter 6, between which ispositioned the throttle valve or attachment, denoted broadly by thenumeral 7, leading to the engine cylinder. This attachment forconvenience, ease of manufacture and installation preferably comprisesan outer body member 8 which may be secured to the adjacent separatedends of the parts 5 and 6, and holds in relatively fixed position a disk10 provided with a relatively large number of small perforations 11throughout its surface. Adjacent this disk or perforated plate 10 is asecond plate 12 of substantially the same size and thickness and havinga corresponding number of perforations 13 and held in any desired manneragainst relative rotation. These plates are held adjacent each other byan eccentric valve stem 14: having a crank 15 operated in the usualmanner by the driver.

This construction permits the plate 12 to move relatively away from thefixed plate 10 where a partial vacuum is formed in the manifold 5 on theintake stroke of the piston and the throttle is opened. It is to benotedthat the holes in the two plates are not in register but are offset withrespect to each other for the purpose of producing a plurality ofcircuitous passages for the explosive mixture as it passes therethrough.

The perforations are preferably about onesixteenth of an inch indiameter, and the area of the perforations in each disk should be equalto the area of the vapor passage be tween the carbureter and the engine.It will thus be seen that when the disks are separated approximatelyone-thirty second of an inch, the engine will be supplied with a fullcharge of vapor.

By thus dividing the vapor into small streams, and reducing thesestreams to films of vapor between the disks, where they unite with otherfilms moving with great velocity in opposite directions, the partialvaporization of the fuel which has taken place in the mixing chamber ofthe carbureter, is effectually completed.

This is not only the case when the engine is being supplied with a fullcharge of vapor, but is equally so when the engine is being suppliedwith a comparatively small charge, because the space between the disksis increased or diminished in accordance with the volume of the charge,the velocity of the vapor at this point remaining substantially thesame. It is of course clear that these air and gas currents will not allmove in the same direction which consequently results in the fact thatcertain currents passing through the holes in the plate 10 move towardeach other in order to pass out through an intervening hole 13 in themovable plate 12. This results in a most intimate and thorough mixing ofthe air and gasolene and owing to the relatively small space between thetwo plates during the 111- take stroke of the engine any globules of gaslene will become completely and thoroug ily broken up and vaporized.

This operation is manually controlled n the modification shown in Fig.1, yet 1t is of course to be understood that the separation of theplates may be automatic if so desired, as shown in the modification inFig. 4, in which case the device acts in connection with a throttlevalve 16 for controlling the amount of explosive mixture allowed to passthrough the manifold 5. Any convenient means may be employed forpermitting a separation of the plates but I prefer to use a mechanismsuch for example as shown in Fig. 4, in which a spring 17 acts againstthe fixed plate and has a shank 18 adjustably connected to the plate 12by means of a nut if desired or the shank may be bent as shown.

' From the above it will be seen that the present invention comprises asimple and practical attachment or valve particularly adapted for use inconnection with the intake manifold of a gas engine for obtaining themaximum efficiency therefrom. This inexpensive device which may be soconveniently installed practically eliminates the chance of any globulesof gasolene entering the cylinders as the intermingling currents passingthrough the perforated plates completely breaks up the same, therebyresulting in the maximum power being obtained from a given quantity ofgasolene. The parts are so positioned, arranged and constructed as topermit ready assembling, disassembling or replacing thereof, as may benecessary, and the invention is believed to accomplish, among others,all of the objects and advantages herein set forth.

\Vithout further analysis, the foregoing will so fully reveal the gistof this invention that others can by applying current ,knowledge readilyadapt it for various applications without omitting certain featuresthat, from the standpoint of the prior art, fairly constitute essentialcharacteristics of the generic or specific aspects of this invention,and therefore such adaptations should and are intended to becomprehended within the meaning and range of equivalency of thefollowing claims.
